With a 9mm heel to a 5mm toe that is trimmable to size 6-12, the kingfoam elite is the new standard in durability and impact protection, the kingfoam elite insoles are rated for twice the impact protection at heavy impact levels vs our normal kingfoam insoles. With upgraded fabric strength, a tough skin protects the inner foam for lasting durability and protection from blowouts. They are also flexible enough to fold and roll ensuring no loss in boardfeel. With a deep heel cup that cradles the entire heel and fits into any shoe, maximum heel protection is ensured. Nearly twice as thick in the heel than normal jaws insoles. Simply place your stock insole onto the kingfoam elite insole and trim around the outside.
